Abstract

A liquid atomizer capable of stabilizing atomization by making constant the amount of liquid fed to an atomizing part at a low cost, wherein a chemical stored in a primary liquid storage part (10) for storing the atomized chemical is filled by a specified amount to a secondary liquid storage part (16) through a liquid feed passage (18), a piston (20) is pushed by an operating rod (42) to turn on a power supply switch (46) when a liquid supply button (40) is slid to the left side, a valve (22) is moved leftward to open a liquid feed passage (24) as the chemical in the secondary liquid storage part (16) is pushed when the piston (20) is moved leftward, and the specified amount of chemical in the secondary liquid storage part (16) is fed to the atomizing part formed of a horn vibrator (30) and a mesh member (32) through the liquid feed passage (24) and a guide groove (26) and atomized there, whereby the atomization can be stabilized by making constant the liquid amount fed to the atomizing part at a low cost.
